...the related code in Xen for this interception? (anything to do with "switch_to_kernel in xen/arch/x86/x86_64/entry.S"?) If no, then how could I intercept that instruction in this case? (2) If a guest app uses "int 0x80" to launch a system call, then is it true that after "init_int80_direct_trap," the int 0x80 is no longer intercepted by Xen, and the app can trap directly into the guest kernel? My understanding is that "init_int80_direct_trap" initializes vcpu''s arch_vpuc.int80_bounce. Could someone please briefly explain how things work after this struct is properl...

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense.
